PROTECTIVE BOTTLE.

Application filed November 20, 1913.

To all whom it may concern Be it known that I, CLARENCE FRnoERIo DAVY, a citizen of the Dominion of New Zealand, and residing at Fitzroy, New Plymouth, in the Provincial District of Taranaki, in the Dominion of New Zealand, have invented certain new and useful Improvements in Protective Bottles, of which the following is a specification.

The invention relates to the class of bottles designed to obstruct refilling.

According to my present invention the interior of a bottle neck has two circumferential shoulders or ledges, upon the lower of which rests a disk valve weighted upon its underside. Upon the upper ledge is a stop disk having radial wings which extend beyond both faces of the disk and which bear against a cap designed to rest upon the top of the bottle neck. A ball weight is located upon the top of the valve referred to and moves freely between the wings of the disk. 7

The cap has a centralhole for the passage of liquid and is secured in position by a metal capsule which is spun over its edge into a ring recess therein and is forced into circumferential groovesin the neck of the bottle. Radial projections from the disk valve and the wings of the stop disk provide passage ways through which liquid may flow from the bottle.

The invention is illustrated in the drawing wherein Figure 1, is a vertical sectional elevation. Fig. 2, a sectional plan on A-A Fig. 1. Fig. 3, a similar view on 13-13 Fig. 1, and, Fig. 1, a perspective elevation of the stop disk.

The valve 1, having a convex upper surface 2, and a weight projection 3 upon its underside, rests upon a seat 4:, formed by a shouldered portion of the passage 5, through the bottle neck 6. A Weight ball 7 rests (upon the top of the valve, and is kept in position by a stop disk 8, having projecting wings 9 the lower ends of which rest upon a ring 10 of cork or the like, on a shoulder 11, in said passage 5. The upper ends of said wings are in contact with the underside of a cap 12, which has an opening 13 for Specification of Letters Patent.

the passage of liquid and is kept in position by a metal capsule 14, the upperedge of which is turned over the circumferential edge of the cap, while its lower part is pressed into recess rings 15 in the bottle neck.

Valve 1, has projections 16 radiating from its circumference to guide it, and to permit of the passage of liquid. The wings upon the stop disk 8, also permit liquid to pass between them and maintain the disk in its correct position, while the cap is being secured upon the top of the neck by means of the capsule. The wings are each formed to a radius upon their inner ends thereby providing a chamber 18 which receives the ball when the bottle is tilted, and enables the valve to lift from its seat for the passage of liquid. The weight 8 upon the underside of valve 1, causes the valve to remain upon its seat until the bottle has been considerably tilted. A cork stopper 19 is held in a well known manner by a metal cap 20 which has a corrugated circumferential edge engaging over a ring flange 21 upon the top of the bottle neck. If desired the passage through the cap may be closed by a tightly fitting cork in the usual way.

What I do claim and desire to secure by Letters Patent of the United States is 1. In a device of the character indicated the combination of a bottle neck, a valve, a shoulder within said bottle neck forming a seat for said valve, a ball weight above said valve, a second shoulder within said bottle.

neck located between the aforesaid shoulder and the top of the bottle neck, a top disk having radially-extending wings projecting above and below the disk and engaging said second shoulder, and a cap on the top of the bottle neck for holding said top disk stationary against said second shoulder.

stop disk having radially-extending Wings name to this specification in the presence of projecting above and below the disk and entWo Witnesses.

gagin said second shoulder, a cap on the. Y 1 top oi said bottle neck for holding said stop CLAREN CE FRLDERIG DAVY' 5 disk stationary, an orifice in said cap, and Witnesses:

means for closing said orifice. J. J. VVATsoN,
